15-keto-13-14-dihydroprostaglandin-f2alpha and Infertility--Female

The objective of this study was to determine the value of using plasma concentrations of PGFM to diagnose subclinical endometritis in the dairy cow, and its relationship to subsequent fertility. A total of 274 cows between 24 to 29 d post partum was divided into 4 groups on the basis of clinical features of the uterus and ovary. Cows in Group 1 (n = 74) had a normal, involuting uterus and a CL on the ovary; cows in Group 2 (n = 51) had a normal, involuting uterus but no CL on the ovary; cows in Group 3 (n = 83) did not have a normal, involuting uterus but had a CL on the ovary; and cows in Group 4 (n = 66) did not have a normal, involuting uterus or a CL on the ovary. A blood sample was obtained from each cow on the day they were placed on the study, and plasma concentrations of PGFM and P4 were determined using RIA. Cows were artificially inseminated (AI) at the first observed estrus after Day 60 post partum, and pregnancy was determined by palpation of the uterus per rectum between 45 and 50 d postAI. Reproductive responses evaluated were conception rate to first service, days open, and percentage of cows pregnant by 90, 120, 150 and 180 d post partum. Data were analyzed using GLM procedures of SAS and a 2 x 2 factorial with contrast procedures. Polynomial regression analysis was used to determine the shape of the PGFM, P4 and fertility curves. There was no difference among mean PGFM concentrations of cows in each group. The rate of decline of plasma PGFM concentrations was lower in cows with an abnormal uterus and a CL on the ovary compared with those without a CL. A lower percentage of cows with abnormal uteri was pregnant by 90 d post partum compared with cows with normal uteri. From the results of this study, it was concluded that plasma PGFM concentrations between Days 24 to 29 post partum were not effective in identifying cows with subclinical endometritis.

Peritoneal fluid from 35 women with endometriosis and from 34 control women was aspirated at laparoscopy and analyzed. No differences in prostanoid levels were found. The peritoneal fluid volume, macrophage concentration, macrophage content, and content of activated macrophages as measured by acid phosphatase staining were all significantly elevated in the endometriosis patients. The macrophages were incubated and the medium was added to the zona-free hamster egg sperm penetration assay. This medium caused a significant decrease in the percentage of ova penetrated in this assay. It is postulated that one of the mechanisms of infertility in women with endometriosis may involve the increased number of activated macrophages and their ability to interfere with sperm-egg interaction.

Prostaglandin F2 alpha (PGF2 alpha) metabolite (13,14-dihydro-15-keto PGF2 alpha) and prostaglandin E2 (PGE2) were assayed in the cul-de-sac fluid aspirated from 15 patients with endometriosis, in saline peritoneal washings of 5 patients with unexplained infertility, and in 5 control subjects. The fluid from the cul-de-sac of patients with endometriosis showed wide variations in the concentrations of PGF2 alpha metabolite and PGE2. There was no correlation between the concentration of these prostaglandins (PGs) and the stage of the cycle. Saline peritoneal washings from patients with unexplained infertility had significantly higher concentrations of PGF2 alpha metabolite than the control subjects. The concentration of PGE2 in the saline peritoneal washings was higher in the group with unexplained infertility than in the control group; however, the difference was not significant. The concentration of PGF2 alpha metabolite and PGE2 in the peritoneal saline washings from patients with unexplained infertility were no different from the concentrations of these PGs in the peritoneal fluid (PF) from patients with endometriosis. PG concentration in PF of infertile patients with or without endometriosis is a new variable for evaluation in these patients.
